We look at the division of 85925351 by 388 
The aim is to understand the frequency of 388 in 85925351.

Let's proceed to step 1:
388 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 388

Advancing to step 2:
85 divided by 388 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 388

Let's proceed to step 3:
388 goes into 859 2 times with a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 776 from 859 to get 83.
Take the next digit (2) from the dividend and append it to 83, then repeat: 832 / 388

Let's proceed to step 4:
When dividing 832 by 388, we get 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 776 away from 832, we end up with 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 388

Advancing to step 5:
When dividing 565 by 388, we get 1 with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
The remainder is 177 after subtracting 388 from 565.
Grab the next digit (3) from the dividend, add it to 177, then carry on: 1773 / 388

Moving on to step 6:
388 goes into 1773 4 times with a remainder of 221.
Record the quotient 4 as the next digit in the result. 
Result so far: 2214.0
If we take 1552 away from 1773, we end up with 221.
Grab the next digit (5) from the dividend, add it to 221, then carry on: 2215 / 388

On to step 7:
388 goes into 2215 5 times with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 22145.0
The remainder is 275 after subtracting 1940 from 2215.
Fetch the next digit (1) from the dividend, attach it to 275 and continue: 2751 / 388

On to step 8:
388 goes into 2751 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 221457.0
Subtract 2716 from 2751 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
If we divide 350 by 388, we get 0 and a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 221457.0
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
The number 388 fits into 3500 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 221457.09
The remainder is 8 after subtracting 3492 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 388, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 221457.09
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
800 divided by 388 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 221457.0902
Subtracting 776 from 800 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
The number 388 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 221457.0902
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
388 can be fit into 2400 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 221457.090206
Subtracting 2328 from 2400 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
720 divided by 388 is 1 with a remainder of 332.
Write down 1 as next digit of the result. 
Result so far: 221457.0902061
If we subtract 388 from 720, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 16:
If we divide 3320 by 388, we get 8 and a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 221457.09020618
The remainder is 216 after subtracting 3104 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 221457.09020618 and a remainder of 2.16e-07.
